We have a setup where we utilize the ability to communicate with Azure hosted VM's (elasticsearch) from our Websites using a VNET. However from time to time the website cant reach the VM's using their internal IP and we get the following errors alle the time:
The requested address is not valid in its context: 10.1.0.5
It seems like something goes wrong with the VNET, we have seen this quite a few times where it "solves itself" but currently we are seing it without it going away for a long period of time.
Any ideas what can be the cause of this, and is there a workaround to get it working again we trieds this:
1. Remove the website from the VNET and adding it again
2. Restarting website
3. Restarting the VM's
